Abstract


Based on the engineering backgrounds of the damaged bridge, a bridge-onbridge method is proposed to reinforce the damaged bridge in this paper. To carry the temporary overload vehicle, the structural type and support of the Prefabricated Highway Steel Bridge is designed. Then, the three-dimension numerical model is built and the numerical simulations are conducted to investigate the feasibility of the design.
